STEAM-ENGINE.

SPECIFICATION forming part of Letters Patent No. 530,961, dated December-18, 1 894.

l Application filed July 13, 1894:- Serial No. 517,4 56- (No model.)

.To all whom t may concern:

Beit known that I, HERMAN NIELsEN, a citizen of the United States, residing at Edgerton, in the county of Rock and State of Wiscousin, have invented a new and useful Steam- Engine, of which the following is a specification. This invention relates to steam engines; and it has for its object to effect certain improvements in engines of the rotary type wherein a head or pressure of steam shall be utilized to its fullest extent, thereby securing the greatest possible amount of power therefrom.

To this end the main and primary object of the present invention is to provide a new and useful engine of the character noted constructed of comparatively few parts while at the same timehaving every adjustment necessary to insure a positive and eicient operation.

With these and other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.y

In the accompanying drawings:-Figure l is a perspective view of a steam engine constructed in accordance with this invention. Fig. 2 is a central vertical longitudinal sectional view thereof. Fig. 3 is a vertical sectional view on the line --x of Fig. 2. Fig. 4 is a similar view on the line y-g/ of Fig. 2. Fig. 5 is a side elevation of the revolving cylinder Wheel with the side cap plate removed showing the radially disposed steam cylinders therein. Fig. 6 is a detail in perspective of the adjustable valve ring detached. Fig. 7 is an inner side elevation of the valve ring and the disk on which it turns. Fig. 8 is a detail in perspective of the crank shaft and shaft block.

Referring to the accompanying drawings, 1v

designates a bearing bracket that is adapted to be suitably supported on any convenient supporting frame or stand for the engine, land said bearing bracket is provided with the opposite parallel bearing arms 2, having squared sockets 3, in their upper ends and adapted to support for rotation there-between the revolving cylinder or casing wheel A4, from.V

which motion may be communicated by a belt or other suitable means to any machinery that is designed to be driven from the engine. The said revolving cylinder or casing wheel 4, is closed at one side and at its open side is adapted to be removably inclosed by the removable side cap plate 5, which serves to firmly position within the wheel, the steam cylinders 6. The steam cylinders 6, are arranged inside of the Wheel radially to the center thereof, and are spaced equally distant from each other. The said cylinders 6, are securely clamped in their regularly spaced and radially disposed positions by means of the segmental clamp plates 7, interposed between the cylinders and clamped tight against one side of the same by means of the clamp screws 8, passing through such plates and engaging threaded `openings in the closed sides of the revolving cylinder or casing wheel.

The radially disposed steam cylinders 6, are open at their inner ends and are provided in the closed side of the wheel 4, with the steam ports 9, that provide for the admission of steam intoV the cylinders and the exhaust of steam therefrom, and said ports 9, communicate with the channel plates l0, that are placed between said cylinders and the closed side of the cylinder or casing wheel, and also communicate with thev side steam ports 1l, which pierce the closed side of said wheel 4, at a point nearer the center of the wheel than the location of the ports 9, there being one of the ports l1, for each cylinder 6, to provide for the admission of steam thereto and the exhaust therefrom. The said ports 11, correspond in arrangement and disposition tok the cylinder ports with which they communicate in order that provision may be made ,for feeding one pair of cylinders and for exhausting the directly opposite pair atthe lsame time. c

The inner open ends of the cylinders 6, accommodate the movements of the solid piston heads 12, and the piston rods 13, pivotally connected at their outer ends as at 14, to the inner sides of said piston heads, and

the other inner ends of said piston rods arevv -theirouter closed ends and at the side next to pivotally centered on the upwardly disposed crankv or crank pin 15, of the stationary crank shaft 16. rlhe stationary crank shaft 16, projects through a central bearing opening 17, in the side cap plate 5, of the revolving cylinder wheel to form a bearing support for that side of the wheel, and the outer end of said stationary crank shaft has fitted thereto the squared shaft block 18, that is adapted to lit in the squared socket 3, at the upper end of one of the bearing arms 2. The squared shaft block 18, is provided with a depending screw plate 19, having a screw opening 20, to receive a securing screw 21, passing therethrough and through an aligned opening in a U-shaped washer plate 22, embracing the block 18, and interposed between the plate 19, and the adjacent bearing arm. The screw 21, engages a threaded opening 23, in one of said bearing arms and serves to securely clamp the block 18, firmly in position to maintain the crank shaft perfectly stationary. By reason of the support for the cylinder wheel described, it will be obvious that the steam which is admitted into the cylinders 6, to .0pcrate upon the pistons therein will transmit a rapid rotation to the cylinder or casing wheel carrying the cylinders, the rotation of such wheel changing the position of the ports 11, so that the proper feed and exhaust of the steam will occur in the manner to be described. urlhe said revolving cylinder or casing wheel 4, has projected from its closed side in which the ports 1l, are formed a cen tral bearing trunnion 24, that loosely turns in one end of the bearing sleeve 25, squared or reduced at opposite sides as at 26, to fit in the squared socket at the upper end of one of the bearing arms 2, in order to be held stationary. The said bearing sleeve 25, is provided at its inner end with theintegral or fixed bearing disk 28, the periphery of which is beveled and is provided with directly opposite steam recesses 29, with the upper of which is connected one end of the live steam pipe 30, and with the lower of which is connected one end of the exhaust steam pipe 31. The said peripherally beveled stationary bearing disk 28, accommodates for movement thereon the adjustable valve ring 32. The adjustable valve ring 32, has its inner periphery beveled reversely to the periphery of the disk 28, so that the said ring cannot work off of the bearing disk on which it is mounted when the various parts of the engine are set up.

The adjustable valve ring 32, is adapted to fit the closed side of the revolving wheel 4, in a steam tight joint, and upon its inner side contacting with the said revolving wheel, the valve ring is provided with diametrically opposite segmental steam grooves 33, which are sufficiently long to connect two of the ports 11 in the closed side of the revolving wheel, and at the terminals of the grooves 33, the said ring is provided with the inneriperipheral steam ports 34, that are adapted to be brought into a registering position with the peripheral steam recesses 29, formed in the central bearing disk 28. The adj ustable valve ring 32, has attached to one side thereof the o-standing fixed lever arm 35, in which is pivotally mounted the spring actuated catch lever 36, the inner end of which is adapted to engage the catch notches 37, formed in the outer face or side' of the disk 28, to hold the ring 32, stationary in its adjusted position.

By the adjustment of the valve ring 32, it will be obvious that the same may be brought to a position to carry either of the ports at the extremities of the steam grooves 33, to a reg# isterin g position with the opposite recesses 29, of the disk 28, in order to quickly reverse or change the rotation of the cylinder wheel, while at the same time the said valve ring may be adjusted to regulate the quantity of steam admitted to and exhausted from the steam cylinders in order to control the speed of the engine or to entirely cut 0E the supply of steam thereto. The said valve ring therefore provides the engine with every necessary adjustment to completely control the operation thereof. It is to be noted that the stationary crank or crank pin of the crank shaft is eccentric to the center of the revolving wheel, and the steam grooves 33, are located diametrically opposite each other directly above and below such crank pin so that the uppermost pair of cylinders will be receiving live steam while the corresponding lower pair of cylinders are exhausting steam.

From the above it is thought that the con` struction, operation and many advantages of the herein-described steam engine will be readily apparent to those skilled in the art, and it will be understood that changes in the form, proportion and the minor details of construction, may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
